01General information

Description

NCI-H2110 是一種源自肺腺癌的人類非小細胞肺癌(NSCLC)細胞系。 該細胞系作為 NCI-海軍醫學腫瘤學分部細胞庫的一部分而建立,廣泛用於研究非小細胞肺癌的生物學特性,以及評估標靶治療和細胞毒性治療的療效。 在標準體外條件下,該細胞系以黏附性上皮單層形式生長,通常在添加 10% 胎牛血清的 RPMI-1640 培養基中培養。

NCI-H2110 的分子分析顯示存在 KRAS 活化突變,這是一種關鍵的致癌驅動因子,會促進 MAPK/ERK 和 PI3K/AKT 訊號傳導路徑的持續活化。 這使得該細胞系成為非小細胞肺癌(NSCLC)模型中的一類,雖對 EGFR 抑制劑具抗藥性,但可能對針對 KRAS 信號傳導下游效應因子的療法敏感。 其突變譜和路徑依賴性使 NCI-H2110 成為藥理基因組學分析中的寶貴工具,包括探索「癌症細胞系百科全書」(CCLE)等大型細胞系面板中的藥物敏感性。

除了用於藥物篩選平台外,NCI-H2110 還被應用於轉錄組學和表觀遺傳組學研究,用以探究染色質可及性、組蛋白修飾及基因表達模式。 其特徵明確的遺傳背景,不僅支持針對激酶抑制劑抗藥性的機制研究,更有助於闡明 KRAS 突變型肺腺癌更廣泛的分子圖景。

Thawing and culturing
  1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

  2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

  3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

  4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

  5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

  6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

  8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

07Quality control and cryopreservation

Sterility

透過基於 PCR 的檢測及基於發光原理的支原體檢測方法,排除支原體污染的可能性。

為確保無細菌、真菌或酵母菌污染,每日均會對細胞培養物進行目視檢查。

Freeze medium
作為冷凍保存培養基,我們使用完全生長培養基(含 FBS)+ 10% DMSO 以確保解凍後的存活率,或使用 CM-1 (Cytion 型號 800100),該培養基含有經優化的滲透保護劑和代謝穩定劑,可提升細胞恢復率並減輕冷凍誘導的壓力。
Storage conditions

若需長期保存,請將試管置於溫度約為 −150 至 −196 °C 的氣相液氮中。僅在轉移至液氮之前,可將試管暫時存放於 −80 °C 環境中,作為短期過渡步驟。

Shipping conditions

冷凍保存的細胞系會以乾冰冷藏,並裝於經驗證的隔熱包裝中,包裝內含有足夠的冷媒,以確保在運輸過程中溫度維持在約 −78 °C。收到貨物後,請立即檢查容器,並盡快將試管轉移至適當的儲存場所。
